You slump as the tentacles pull away from your body, having drained you of all of your intelligence and… something else. You cannot think. Only listen and obey.
Your body shivers, as it begins to melt and flow. It happens in a daze, but in the end, all that remains of you is a fish, not unlike the ones in the lake. You swim up to the surface, swimming lazily in a circle, waiting for any creatures to enter the lake.
You can feel your Master deep below you, ready to snatch any creatures who enter the lake. You will serve as Master's eyes and ears.
